Maxillary dentition sequential distalization using clear aligners and mini-implants in an adult with Class II Division 1 malocclusion
Class II Division 1 malocclusion is characterized by maxillary incisor protrusion and excessive overjet, leading to common esthetic concerns among patients. Clinically, determining between extraction and nonextraction is a complicated treatment decision, especially in patients with borderline diagnoses. This case report describes the treatment of an adult borderline case with Class II Division 1 malocclusion and protruding maxillary incisors. To ensure esthetic prognosis, the virtual treatment goal for maxillary incisors was set on the basis of esthetic criteria. In addition, a 3-dimensional evaluation was conducted to acquire comprehensive information on the arch volume for scientific treatment decision-making. This patient received a nonextraction treatment involving maxillary dentition sequential distalization and proper dental expansion aimed to retract the protruding maxillary incisors to the ideal esthetic position. The treatment was successfully conducted using clear aligners and mini-implants. Ultimately, harmonious dentofacial esthetics and ideal functional occlusion were achieved after 33 months of treatment and maintained after 2 years of retention.
